Fossil Ammonite Cut and Polished Pair 1.875 Inch

Ammonites are cephalopod mollusks, relative of the present day nautilus, octopus and squid, that flourished and perished in the Mesozoic Era (160 million years ago). Their shells were often spiraled and ridged, like a ram’s horn, and named after ancient Egyptian god Ammon who typically worn ram’s horns. The fossil iridescence would not have been visible during the animal’s life, additional shell layers would have covered it.
